Fixed Inductors Procurement Notes

Verify the suffix 'F' confirms RoHS compliance status and lead-free terminations as specified by the manufacturer. Confirm the 'J' suffix indicates the required ±5% tolerance level. Ensure the ordering part number matches the exact inductance value of 51 nH. Cross-reference the datasheet for specific packaging quantities if applicable. Validate that the component meets the required operating temperature range for the target application environment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 51 nH is required for high-frequency operation. The 0805 footprint suits space-constrained PCB layouts. Choose based on the need for a ceramic core to minimize magnetic interference compared to air-core alternatives. Consider the 120 mΩ DCR limit for current handling requirements. Verify compatibility with automated pick-and-place assembly processes due to the chip form factor.

Fixed Inductors Part Context

This part belongs to the CT0805HQ series of SMD wire-wound chip inductors designed for high Q applications. The series offers various inductance values ranging from 2.5 nH to 51 nH in the 0805 package. The 'HQ' designation highlights the high-quality factor performance suitable for RF circuits. The 'F' suffix denotes the RoHS-compliant variant of the standard HQ line.

Fixed Inductors Replacement Considerations

Direct substitutes include other 51 nH ±5% 0805 ceramic core wire-wound inductors from manufacturers such as Bourns or Murata. Ensure replacement parts match the 120 mΩ DCR maximum and 2050 MHz SRF minimum specifications. Verify that alternative components also offer RoHS compliance if environmental regulations apply.
